The Consistency between Covid-19 RT-PCR and IgM/IgG Quick tests results

Abstract

The aim of this retrospective study was to analyze the results of tests for SARSCoV- 2 performed during 07.04.2020- 20.06.2020 in the Department of the Emergency from Bucharest University Emergency Hospital. We detected 173 men and 133 women that were tested with both RT-PCR and serologic tests. The results were concordant for 287 samples (93,8%) that were collected from subjects for whom the diagnosis of COVID-19 was subsequently confirmed (10) or infirmed (277). We found that the most frequent signs and symptoms of patients with COVID-19 were at the respiratory (e.g. dyspnea), neurological (e.g. vertigo, cephalgia) and gastrointestinal (e.g. abdominal pain, vomiting, high volume of the abdomen) systems. There was no situation with positive RT-PCR and IgG and negative IgM results. In our study the RT-PCR and quick serological tests were concordant in 93,8% of cases. The combination of RT-PCR and serological testing can enhance the accuracy of COVID-19 diagnosis.
